English ivy (Hedera helix) is native to most of Europe and southwest Asia. Although it is often used as a landscaping groundcover in the United States, it is also an invasive species that is considered a noxious weed in some areas.

Based on preliminary animal studies, English ivy leaf extract may have antimutagenic (anticancer) and antioxidant properties. In addition, it may also be beneficial for children with asthma or adults with chronic obstructive pulmonary disease. However, more research is needed in all of these areas to assess English ivy's potential benefits.

These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Tradition / Theory
The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

There is no proven safe or effective dose for English ivy in children.

Safety
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

The most frequently reported adverse effects related to English ivy are allergy symptoms, such as allergic contact dermatitis, asthmatic bronchitis, or allergic rhinoconjunctivitis (inflammation of the lining of the nose and the mucous membrane that covers the front of the eye and lines the eyelids). Gardeners and those with frequent exposure to English ivy may have a high risk of sensitization and should wear appropriate protective clothing.

Use cautiously in patients with cancer or taking antineoplastic (anticancer) agents.

Pregnancy and Breastfeeding

English ivy is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
